The decision this case can inform
Use this record when reviewing the reach, location, and operability of permanent or temporary valves, sample points, grease points, and service connections.
Final MSHA fatal-accident investigation. It establishes the hazardous access arrangement and planning failure; the correct fall-control design remains site- and task-specific.
What the public record actually establishes
- F1
A temporary air-line valve and coupling were positioned roughly 6.75–7 feet above the walkway.
- F2
The connection was outside the handrail beside a walkway inclined about 29 degrees.
- F3
No pre-task risk assessment or fall protection addressed the access required to operate the connection.
- F4
The welder/repairman fell 37 feet.
Facts and reported results are kept separate from the lesson a plant may choose to test.
Operating context
A temporary air-line valve and coupling were located about 7 ft above an inclined walkway outside the handrail.
Intervention or finding
MSHA found no pre-task risk assessment and no fall protection while the worker accessed the elevated connection.
Documented result
A welder/repairman fell 37 ft.
Plant interpretation
Design valves, sample points, grease points, and temporary connections for safe reach and stable work positioning.
Transfer boundary
The applicable fall-protection solution is task- and jurisdiction-specific.
Questions to verify at your plant
These are decision checks, not operating instructions. Resolve them through local risk assessment, technical review, and authorization.
- 01
Can the control be operated from a stable, guarded position within normal reach?
- 02
Does a temporary installation create a new climbing, leaning, or handrail-bypass task?
- 03
Who reviews human access before a temporary connection is released for use?
- 04
Are similar valves, sample points, and lubrication points included in a plant-wide access-by-design audit?
